Sorry...couldn't help myself. You can take multiple pieces of various colors of organza (reds, oranges, and possibly the occasional yellow or white) and stitch them together in a sort of loose chaotic overlapping chain. Getting crazy, you could then tightly fold/bunch the chain up in a manner similar to the classic unending handkerchief trick. Tie one end to your hand/wrist, and securely stitch an appropriately sized lead fishing weight (possibly wrapped in foam for safety) to the other end. Properly executed, throwing the lead weight could cause the chain to impressively unfurl simulating a plume of fire. However, such a thing would very probably thoroughly upset con staffers, so it should probably be relegated to situations like masquerades.
